I Help You, You Help Me

Was trying to get my BLM AF from AV, so I was shouting for a tank.  Found one but he said he'd only help me if I helped him get his PLD AF first.  I felt a little taken advantage of that he expected me to give up an hour of my time fighting his bull shit PLD body NMs...when he in turn helped me for a total of 3 minutes to run through AV.
